The geology of this site generally consists of northeasterly dipping Cretaceous strata, part of the northern limb of the Wealden-Boulonnais dome. ]]> 2017-03-06 02:19:40 UTC https://padlet.com/brayantirano/mw49604zpe3a/wish/157908998 brayantirano https://padlet.com/brayantirano/mw49604zpe3a/wish/157909425
  •  Characteristic Geotechnical include:
    • Four geological strata, marine sediments laid down 90–100 million years ago; pervious upper and middle chalk above slightly pervious lower chalk and finally impermeable Gault Clay. A sandy stratum, glauconitic marl (tortia), is in between the chalk marl and gault clay.

  • Surveying undertaken in the 20 years before construction confirmed earlier speculations that a tunnel could be bored through a chalk marl stratum.
